WOW!
thanks @dalto , you are giving me hope I can use BTRFS and Baloo at the same time!
What I had before was that with each snapshot Baloo was indexing again the same “/home” files as if they are another copy. Searcing for a unique file in Dolphin caused the same file to appear n+1 times - all pointing to the same file - where “n” is the number of snapshots.
I will try and read more about how to… !
Thank you very much!
You have to design your system. If you put snapshots with user readable privileges inside the part of your system that baloo is indexing then that will happen. But…why would you do that?
Given that I am not that techie I just followed the defaults!
It wasn’t me. I did nothing!
I don’t know how to do it. Sorry!
I don’t think there are any defaults for snapshots.
Honestly I don’t know.
All I remember when I tried EOS a few months ago I just made a fresh install, and selected BTRFS and kept clicking Next till rebooted, then copied/downloaded my files.
BTRFS worked great but without Baloo.
May be I need to read more.
EOS doesn’t include anything that create snapshots.
You would have either have had to install something or taken manual snapshots.
That being said, I think I remember a conversation like that in the past.
Can I say this is the solution to the problem?
That is the opposite of the solution. That is what causes the problem. 
Maybe I installed snapper but I assure you I just followed defaults!
snapper makes the snapshot directories only readable by root so baloo would never index them. I found the old topic:
It looks like you might have been using timeshift. However, we never actually confirmed that the issue was caused by btrfs, that was just a theory.
Maybe language problem or I miss-expressed.
I mean that NOT doing this will sort the problem!
Or that this was the cause of the problem!
Right?
Sorry, English is not my mother tongue.
Honestly I can’t remember but look at the links below. Many users reporting the same at KDE.
Google search
KDE 1
KDE 2
KDE 3
Well, the most important thing for me now, nobody should think I am blaming anybody, any technology, any app or anything.
As you mentioned earlier that you already have BTRFS and Baloo and NOT having this problem reported by several users, so I may conclude that:
I just brought this out of hope to make it easier for normal “just users”, out of my beliefe in Linux, out of my love to Linux. (no need to mention again EOS and this forum)
I will appreciate if you have a link or two for me to read (hope they would be simple, with clear specific steps… for the average Joe to understand and apply)
Finally, I will read more and try again and again and…
Thank you for your time and I apologise for taking a lot of of your time.
I see. That has nothing to do with snapshots. It seems that baloo triggers reindexing because of the way it identifies devices.
That may have been your actual issue.
Seems to be the case.
I will try read more to have it as you have without isues of reindexing.
Thank you.
